My name is David Irvine, and I am the son of James D. Irvine of Sarnia, Ontario. I am compiling my family history and family tree for the Irvines in Lambton County, Ontario, Canada. I can trace the family back to its arrival in Lambton County in about 1850. The family is part of the Irvines of Drum. Anyone with any information that might assist can contact me at dirvine21@cogeco.ca
